If i stopped smoking yesterday can i pass a drug test in 25 days?

Depends on what type of test you are taking and how long you were smoking before that. If it is a hair test, then chances are that you will not pass it. Hair tests go back up to six months. A urine test is a toss up right now, depends again because a urine test can reach as far back as three months in some cases. If you were a habitual smoker then chances are that you may still have it in your system, it compounds the issue if you are overweight too. Still, 25 days is a lot to work with if you do some dieting and sweat off some of the remaining fat deposits in your body. Drink plenty of water and do plenty of exercise that makes ou sweat. If you make use of those 25 days, you should be able to pass that urine test. Now if its a mouth swab, then you have nothing to worry about as those test only reach back three days (at the very most). I would suggest making the most use of your time now.
